howdy, perhaps someone has has experience this problem. 2005 Sequoia Limited 4x4. When accelerating my drivetrain makes a noise. The sound increases with speed and goes away when you let off the accelerator. I have no play in my rear opinion, u joints, and all of my drivetrain fluids are at the correct level. Transmission shifts fine. No hard or delayed shifting. All gears work fine. 4x4, 4x2, L, and H all work correctly. The sound occurs at all speeds.
Any ideas?
